IMPROVEMENT IN WATER-WHEELS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern.-

' Be it known that I, V. M. BAKER, of Preston, in the county ofFillmore, and State of Minnesota, have invented a new and usefulImprovement in `Water- Vheels; and Ido hereby declare that the followingis a full, clear, and exact description thereof, which will enableothers skilled in the art to make and use the same, reference being hadto the accompanying drawings, forming a part of this specication, inwhich- Figure 1 is a top View of my improved waterwheel.

Figure 2 is a horizontal section of the same, taken through the line a:x, fig. 3.

Figure 3 is a vertical section of the same, taken through the line y y,iig'. 2. l

Figure 4 is a detail sectional view of -the same, taken through the linez z, fig. 3.V

Similar letters of reference indicate corresponding parts.

My invention has for its object to improve the construction ofhorizontal water-wheels, so \as k to make them more efficient inoperation, enablingithem to utilize a larger proportion lof the water,and vbringing' them more fully under the control of the operator; an

It consists in the construction and combination of various parts of thewheel, as hereinafter more fully described. l

A is the wheel, which is connected with the shaft B vby the arms al.

The lower end of the shaft B revolves in the 'step O, audits upper endin the bearing D, 'supported by and rigidly attached to the cap of thewheel-case E.

The bearings D are made iu'parts adjusted by setscrews, as shown in fig.1, for convenience in adjusting the shaft B. 1

The`rim a2 of the wheel is made with au incline or Hare, extending fromthe top curve of the long buckets F to the top of the wheel.

F are the long buckets, which are made with al double curve, as shown iniig. 3, and their inner edges are securely attached to the rim' a2` ofthe wheel A.

G are the short buckets, which are attached'ithe long buckets F justbelow their upper curve, as shown in 3, and which do not extend to therim a2 of the wheel A, as shown in fig. 4.

H are the chute-plates, which are made straight, and which are placedbetween and are secured to the top and hottomiianges of the case E.

l is a tube, extending below the wheel A, and which is made witha angeupon its upper end, to support the lower ange of the case E'.

The inner'ends of the chute-platesH shouldbe rounded ofi', to correspondwith the curve of the wheel A .The outer ends of the chute-plates Hshould also be rounded oit", to admit the water more freely.

J are the gates, which slide along one' chute-plate,

so that the entrance of the water to the wheel may be prevented, whendesired, by their 'rounded inner ends coming in contact with the nextchute-plate.

The gates J are guided in their movements by grooves formed in the upperand lower auges of the case E, and to' their outer' ends, at top andbottom,

are rigidly attached arms K, by which they are conf fits and works uponthe case of the bearings D, as

shown in fig. 3.

rllhe hoisting-ring L may be operated to open and close the gates, bymeans of a gear-wheel and rack, O, or other convenient means. f

=-Havingthus described my` invention,

What I claim as new, and desire to secure by Letters Patent, isi- 1. Thecompound-buckets F G, formed'by'the combination of' the longdouble-curved buckets F and the short buckets G with each other` andwith the body of the wheel, substantially in the manner herein shown anddescribed, and for the purpose set forth.

2. The gates J, formed with curved inner ends and with the projectingarms K, connected with the hoisting-ring L, by means of the rodsM,whether the connecting-barsN be used or not, substantially as hereinshown and described.

3. vThe straight chuteeplates H, in combination with Athe gates J andcase E, substantially as herein shownets F to the top of the wheel,substantially as herein shown and described, and for the purpose setforth.
